I think everyone has at least one favorite song that reminds them of a person, place or thing. And that person, place or thing most likely changed you in some way.
Music can take you out of the dumps, or it can make you sad but it can change you. Wouldn’t it be cool if we had a ‘world’ song that everyone loved and it changed the world? ; )
Music is the universal language. Something that everyone can identify with. What is your favorite song? I have so many but if I had to select right now, I would say, ‘White Rabbit’ sung by Grace Slick and the Jefferson Airplane.
